AIX Display Postscript

[henry at yogi.fhhosp.ab.ca]

I've got an RS/6000 on loan (no manuals), and was wondering how I can use its
"display postscript" to preview PS files on the screen.  I'm familiar
with Sun's "pageview" and was wondering if there's something equivalent.
Pageview displays a postscript file just as though it was printed on
a postscript printer.

Thanks,
